University Testing Labs - Vibration Research

Applicable Test Lab Vibration Control Software

Sine

Enter two values out of the four between Acceleration, Frequency, Velocity, or Displacement, and the calculator will do the rest.

Sine Resonance Track & Dwell (SRTD)

Automatically detect transmissibility peaks from a sine sweep, and then dwell tests (time or cycles) run at those resonances.

Random

Measure your products fatigue and calculate its lifespan. Commonly used life acceleration techniques are applied to shorten test time.

Shock

Run standard classical shock pulses as well as (optional) user-defined or SRS synthesized transient pulses.

Field Data Replication

Reproduce, in your test lab on your shaker, the actual acceleration waveform you measure in the field.

Full Software Package & University Syllabus

The following laboratory manual is a brief introduction into the realm of vibration testing and the use of software for vibration control. It is our hope that with access to VibrationVIEW software and this manual, the student may become better acquainted with the concepts of vibration testing, and even delve into some of the more complex areas of this field.

Mix & Match Controllers with Shakers

Each four-channel module can be used independently on separate shakers or linked into a single stack for jobs requiring a higher channel count (up to 128 channels combined). This economic solution creates substantial cost savings for our customers.

File Sharing and Reporting

All systems include our full, robust reporting package which automatically produces presentation-ready, sophisticated reports at the end of a testing sequence. Users select one of our pre-packaged report templates with options to enter important data such as technician, customer name, time, date, test parameters, and more, or creating their own custom, branded reports. VibrationVIEW also allows report generation from PC’s not connected to the controller.

Trial Rental Keys

The VR software packages can be configured for as many or as few test modules as you’d like (à la carte). You may add more at any time in the future.

Lifetime Hardware Warranty

Vibration Research warrants the controller hardware to be free of defects in materials and workmanship for the lifetime of the product.

Bulletproof Inputs

200V tolerant self-resetting fuse protected inputs protect your controller from transients

Software Key Structure

Our control software modules are activated by electronic keys, so you can “rent” modules if you find you have short term needs for specific tests. Not sold on rental or purchase? Feel free to try it out for a week or two.

Remote Interlocks

Shut down your shaker, amplifier and blower as a scheduled function upon the completion of any test saving significant facility costs.

Test Sequencer

A test sequence provides the capability to automatically execute a sequence of tests. All of the tests may be the same type of application or you can switch modes as part of the test sequence.

A few University Labs using VR

Instant Degrees of Freedom

Something is awry with a PSD estimate that achieves total in-tolerance immediately after the test begins or immediately after a change in level, and this can hide dangerous over or under test conditions within specific frequency bands, and should be voided. The proper method of dealing with level changes, as well as a PSD estimation method that accurately and quickly estimates the true signal PSD significantly faster than the traditional averaging method is Instant Degrees of Freedom^® (iDOF).

Copy > Paste with Excel & Word in VibrationVIEW

Copy & Paste Vibration Test Profiles and Graphs into and out of Microsoft Word & Excel. This is especially useful when sharing profiles with colleagues or entering from a customer.

WMU CubeSat Vibration Collaboration

A team of Western Michigan University (WMU) students recently visited VR to run a set of vibration tests as part of their CubeSat project. With advice and direction from VR, the students ran an off-the-shelf spectrometer through a series of NASA-STD-7001B random vibration tests.
